Abstract (en)
[origin: US10199999B1] One example includes a transconductor system. The system includes a first transconductance amplifier that generates a control current in response to a first input voltage. The system also includes a second transconductance amplifier that generates an output signal in response to a second input voltage. The system further includes an intermediate amplifier that generates a control voltage in response to the control current and a third input voltage. The control voltage can be provided to the first and second transconductance amplifiers to set a transconductance of each of the first and second transconductance amplifiers to be approximately equal.
